American teens are getting less sleep than ever, new research from the University of Minnesota School of Public Health shows.
Why it matters: U of M ProfessorRachel Widome, a lead author of the study, said the findings point to a "public health crisis."
By the numbers: Just 22% of 18- and 19-year-olds reported getting the recommended 7 hours of sleep between 2021 and 2023.
Among 12- and 13-year-olds, the share was just over 37%.
Plus: Black and Latino teens and teens whose parents have less formal education were increasingly less likely to get enough sleep.
What we're watching: While there isn't a magic fix, researchers say later school start times can help.
"Without broader structural changes, we risk setting up a generation of young people for long-term challenges in health, learning and overall well-being," Widome said.
